Development of lowland weed management and weed succession in Japan

Abstract: Since the introduction of rice production in Japan, lowland areas have been managed for rice production with the purpose of better rice growth, as well as lesser weed infestation. Rice is cropped every year in lowland fields by repeated cultivation of a single crop, with high yields and without soil sickness usually being observed in upland fields.This is probably because the irrigation water supplies various nutrients for healthy rice growth and the drainage washes out and removes harmful factors. However, un… Show more

“…On the other hand, the distribution and community succession of farmland weeds is closely related to the use of herbicides. As a result of the dif-ferent weed-controlling spectrum of each herbicide, some originally dominant weeds become less dominant due to herbicidal control, but some herbicide-resistant weeds gradually develop from co-occurring weeds into dominant weeds after the long-term use of a particular type of herbicide in a certain area (Watanabe 2011). Therefore, according to the distribution of the weeds, a preliminary judgment can be made about the use of herbicides in the area.…”

“…The risk of grain yield loss due to weeds is greater for DDSR than MTR (Rao et al, 2007). Some weed species infesting upland crops, such as E. indica, D. sanguinalis, Eclipta prostrata, and F. dichotoma, are troublesome in DDSR (Kraehmer et al, 2016;Rao et al, 2007;Watanabe, 2011), and are represented by larger seedbanks. Some principal rice weeds, which are able to produce large numbers of small seeds, become even more problematic in DDSR, such as Cyperus iria (Chauhan and Johnson, 2009), F. miliacea (Chauhan and Johnson, 2009), and Ludwigia prostrata (Li, 1998).…”

“…Although weed community succession in rice fields under different planting systems has been studied in many countries (Kraehmer et al, 2016;Rao et al, 2007;Watanabe, 2011), weed seedbanks under different rice planting systems have seldom been compared. Rice cultivation in Jiangsu Province, China, is a useful model system for understanding weed seedbank composition as a response to different rice planting systems.…”

“…in Japan, and rice has been successfully cultivated in succession in a sustainable way, owing to the function of flood irrigation (Watanabe 2011). Then, because of a decrease in rice consumption, the rotation of rice with upland crops has become a common practice throughout the country.…”
